25 | /* This file contains the main() function for the perl interpreter. |
26 | * Note that miniperlmain.c contains main() for the 'miniperl' binary, | |
9f99f3e9 DM |
27 | * while perlmain.c contains main() for the 'perl' binary. The typical |
28 | * difference being that the latter includes Dynaloader. | |

30 | * Miniperl is like perl except that it does not support dynamic loading, |
31 | * and in fact is used to build the dynamic modules needed for the 'real' | |
61296642 | 32 | * perl executable. |

34 | * The content of the body of this generated file is mostly contained | |
35 | * in Miniperl.pm - edit that file if you want to change anything. | |
d6158b17 | 36 | * miniperlmain.c is generated by running regen/miniperlmain.pl, while |
9f99f3e9 DM |
37 | * perlmain.c is built automatically by Makefile (so the former is |
38 | * included in the tarball while the latter isn't). | |
